Premium 3-stage Big Blue replacement set
Sediment filtration with coconut-shell GAC and coconut carbon-block polishing
This premium three-cartridge set restores one complete filtration cycle in compatible whole-house systems using standard 10″ × 4.5″ Big Blue housings. It combines sediment protection with two coconut-shell carbon stages for chlorine-related taste and odor treatment.

Three-stage filtration
Particle prefiltration followed by two premium coconut-carbon stages
Install the cartridges in the correct flow order: sediment first, coconut-shell GAC second, and coconut-shell carbon block third.
Stage 02
25-Micron Coconut-Shell GAC
Provides a relatively high-flow granular carbon stage that helps reduce chlorine, unpleasant taste, unpleasant odor and many common VOCs.
Stage 03
10-Micron Coconut Carbon Block
Provides denser final-stage contact for additional chlorine-related taste and odor polishing before water reaches household fixtures.
What is included
One complete premium Big Blue replacement set
- ✓One SED5-10BB 5-micron melt-blown polypropylene sediment cartridge
- ✓One CGAC-10BB 25-micron coconut-shell granular activated carbon cartridge
- ✓One CACB-10BB 10-micron extruded coconut-shell carbon-block cartridge
- ✓Three cartridges total—one complete replacement cycle for a compatible 3-stage system
Key benefits
Big Blue capacity with two premium coconut-carbon stages
Complete three-filter set
All three cartridges are included for one scheduled replacement cycle.
Sediment protection
The first stage helps protect both carbon cartridges from suspended debris.
Coconut-shell GAC stage
Loose granular carbon supports practical whole-house flow and broad chemical adsorption.
Coconut carbon-block stage
The final block provides denser contact for additional taste-and-odor polishing.
Big Blue capacity
The 10″ × 4.5″ format provides substantially more media than standard slim cartridges.
Drop-in replacement
Fits compatible industry-standard 10″ × 4.5″ Big Blue housings.
Reduction guide
What the complete filter set helps reduce
Actual performance depends on source-water chemistry, sediment load, chlorine level, pressure, flow rate and remaining cartridge capacity.

- ✓Pressurize slowly, inspect for leaks and flush carbon fines to drain
Standard vs. premium set
Choose the three-stage set that matches your priorities
Both sets use the same 5-micron sediment first stage and fit standard 10″ × 4.5″ Big Blue housings.
Uses standard GAC and a standard CTO carbon block. Best suited for value-focused everyday chlorine, taste and odor filtration.
Uses coconut-shell carbon in both carbon stages and is positioned for enhanced taste-and-odor polishing.
Compatibility
Fits compatible three-stage Big Blue whole-house systems
Confirm the housing size and flow order before purchase. This set does not fit standard 10″ × 2.5″ slim housings.
STD
Standard Triple-Stage Alternative
Choose SGC-10BB when lower product cost is more important than the coconut-carbon upgrade.
S
Individual Sediment Filter
Replace the first stage separately when heavy sediment causes it to load before the carbon cartridges.
CG
Individual Coconut GAC
The premium second-stage CGAC-10BB cartridge may be replaced independently when needed.
CB
Individual Coconut Carbon Block
The premium final-stage CACB-10BB cartridge may also be replaced separately.
